## Affected

- johnwwweissberg Print Science Designer: through 1.3.152

## Description

The Print Science Designer plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.3.152 via deserialization of untrusted input through the 'designer-saved-projects' cookie. This makes it possible for unauthenticated attackers to inject a PHP Object. No known POP chain is present in the vulnerable software. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.
